Expert Solutions for Repairing Large Holes and Cracks in Tree Trunks

Understanding the Causes

Large Holes: These usually occur due to improper pruning. Cutting too close to the tree’s trunk can lead to internal decomposition and hole formation.

Vertical Cracks: These can be caused by lightning strikes, freeze/thaw cycles, or construction damage. In Central Texas, ice storms with subsequent freezes can cause the trunk to crack as trapped water expands.

To Repair or Not?

Tree Trunk Holes: While some holes can become natural habitats for wildlife, holes that don’t seal correctly can allow water inside, accelerating decay. In such cases, filling the hole can help prolong the tree’s life.

Tree Trunk Cracks: Trees typically seal over damaged cracks naturally. However, cracks with jagged edges or those that allow water and pests inside may need intervention.

Wilder Tree Company’s Repair Process

Cleaning and Preparation: We start by cleaning the area, removing any dead or wet wood, smoothing the wound’s edges, and removing loose bark to prevent pest infestation.


Filling the Damage: We use expanding foam (never concrete) to fill the cleaned area. The foam is left to dry, which may take 3-10 days depending on the size of the wound.


Sealing and Painting: After the foam dries, we trim it to blend with the tree’s natural appearance. We then seal the foam with a protective paint that matches the tree’s bark.


Additional Care: We also perform routine maintenance like pruning deadwood and provide fertilizer treatments to aid the tree’s natural healing process.


Cost and Longevity of Repairs

Pricing: The cost of repairing a medium-sized hole or crack typically starts at around $200 plus materials, varying based on the tree’s location and the extent of the damage.

Durability: While the longevity of repairs can vary, addressing problematic cracks or holes proactively helps prevent further damage and prolongs the tree’s life.
